• Embedded link rated suspicious by URL analysis: http://perpustakaan.pn-tapaktuan.go.id/repository/exploit-roblox-hack-apk_GM431946152.pdf - network signal, weight 0.40, confidence 0.60
• Embedded network infrastructure: https://netcdn.tw/app/431946152/hack-week-2021-roblox-game-hack, http://perpustakaan.pn-tapaktuan.go.id/repository/exploit-roblox-hack-apk_GM431946152.pdf, http://perpustakaan.pn-tapaktuan.go.id/repository/coin-master-firebird-card-free_GM406889139.pdf - static signal, weight 0.35, confidence 0.60
• Document active content: uri-action - static signal, weight 0.30, confidence 0.60
• Packing/obfuscation: high-entropy-blob - static signal, weight 0.25, confidence 0.55

Dynamic analysis

No runtime behaviour was captured for this sample, so the analysis above is static only. That is a limit of this run rather than evidence the sample does nothing.
